Into Unscientific

  Chapter 284 Unexpected direction

   Ahhhh.

  As the mantra of a certain Shinigami elementary school student.

   These three words have almost a deterrent effect similar to "Daoist friends, please stay behind" to Xu Yun, who is a future generation.

   And if, on the basis of this word, the speaker is limited to wheat, then its deterrent effect will be even greater.

   Almost at the moment of hearing this sentence.

  Xu Yun's relaxed expression suddenly froze, and a bad premonition emerged in his heart.

   Then he turned his head mechanically and looked at the simple wooden shed where the sound came from.

  I saw this moment.

  Mai Mai was standing in front of a wooden table in the shed. The Fu Qingwuwei Xubo Taishang Cihuangdaojun who had not yet attained enlightenment was frowning and looking at the black and white photos on the table with a puzzled expression.

at the same time.

   Riemann, who was a few steps away from Wheat and was packing up Gauss's manuscript, seemed to have noticed the abnormality of Wheat.

  So he put down the manuscript in his hand, walked to Mai Mai, and the two started talking like this.

  Wheat first raised a photo in his hand, then pointed to the observation record on the table and said something.

soon.

   Riemann's expression gradually became serious.

   After a while.

  Riemann made a waiting gesture towards Mai, walked quickly to Gauss not far away, whispered a few words, and brought his teacher back to the shed.

  See this scenario.

  Xu Yun suddenly couldn't stand still, and hurriedly walked towards the shed.

  When he entered the shed, Mai just finished talking to Gauss about something.

   I saw Gauss propping his hands on the edge of the table, leaning forward slightly, observing something.

  Xu Yun didn't bother when he saw this, but nodded slightly to Mai Mai and Riemann, and then stood quietly and waited.

  At this time, Gauss was concentrating on looking at the desktop, and did not notice Xu Yun's appearance at all.

   After looking at the photos for a while.

  He moved some of them to the front, took out a pair of magnifying glasses from his chest, and started to observe more carefully.

   More than ten minutes later.

   Gauss frowned and straightened up from the table.

  I saw the prince of mathematics pressing his thumb on his cheek, and his index finger gently touching his chin. His tone was full of confusion:

   "Strange, what's going on with this Erlente thing?"

   But while talking, he noticed Xu Yun beside him, and his eyes lit up immediately:

   "Hey, classmate Luo Feng, when did you come?"

   "Not long after I arrived, I was chatting with Mr. Airy in front of me."

  Xu Yun answered his question hastily, then pointed to the photo on the table and asked:

   "Mr. Gauss, this is."

  Gauss pondered for a moment, picked up a photo from the table, and said to Xu Yun:

   "Student Luo Feng, take a look at this."

  Xu Yun took the photo and looked at it seriously.

   After ten seconds.

  He raised his head again, and the expression on his face became more and more bewildered:

   "Mr. Goss, is there something wrong with this photo?"

  Gauss gave him the number 2963 for this photo, which was taken by the Roman Observatory in Italy in 1843.

  The position of Pluto is on the upper right side of the picture, and there are no other celestial bodies around.

   In Xu Yun's opinion.

  In addition to the black and white background, the accuracy and field of view of this photo are perfect. It can be said to be the standard template for the early records of Pluto.

   But look at Gauss' expression.

   Something seems wrong with this photo?

   Then Gauss glanced at him, handed his magnifying glass to Xu Yun, and said:

   "You look again with a magnifying glass, pay attention to the upper left of Pluto."

  Xu Yun took the magnifying glass and looked again.

   This time, he finally found some subtle anomalies:

  On the upper left of Pluto's light spot, there is a tiny bulge!

   This convexity occupies about 1/5 of the area of ​​the light spot, and it is almost impossible to distinguish without careful observation.

  The opposite is the upper right corner of Pluto, where it is a smooth arc.

  See this scenario.

  Xu Yun's heart skipped a beat, and the bad thoughts became clearer.

  Gauss did not notice Xu Yun's stiff expression, but pointed to the photo, and asked:

   "How about it, did you see it?"

  Xu Yun could only nod his head, think for a moment, and said to Gauss:

   "Professor Gauss, is it possible that the aperture of the camera is abnormal when shooting?"

   "After all, this kind of image has pixel difference after zooming in. It doesn't seem to explain anything?"

  Gauss shook his head decisively when he heard the words, pointed to the other images on the table and said:

   "You're wrong, Luo Feng, it's not just this photo that has abnormal bumps."

  "According to Maxwell's observations, there are at least eight photographs where this anomaly can be observed, and they are generally concentrated between 1840-1845."

  Xu Yun slightly trembled the hand holding the photo upon hearing this.

   Then he laughed dryly, looked at Gauss, and said:

   "So Professor Gauss, you mean"

  Gauss picked up a photo, stared at it for a few seconds, and then said slowly:

   "If I'm not mistaken, the anomaly on the image may be a companion star of Conan's star—note, it's a companion star, not a satellite."

   "And estimate from the image. Its diameter may not be much smaller than Conan Star."

  Xu Yun heard the words, his eyes and nose, his mouth and his heart, with a calm look on his face.

  But at this moment, there was a storm in his heart.

  Mom!

   Something big happened!

   Mentioned earlier.

  The solar system beyond Neptune can be further divided into the Kuiper belt and the Oort cloud zone from near to far.

  The celestial bodies in this part of the region are called trans-Neptunian celestial bodies because their positions or orbits exceed the orbit of Neptune.

   Among them, Pluto is a standard template of trans-Neptunian objects.

  Its average distance from the earth is close to 40 astronomical units, the apogee is about 7.376 billion kilometers, and the perigee is about 4.437 billion kilometers.

   At the same time, the time required for Pluto to orbit the sun is also the longest among all planets:

   It takes about 248 Earth years for one revolution, and six more Earth days for one rotation.

  That’s why Xu Yun is quite depressed sometimes—he said 30,000 updates per day and didn’t say it was an Earth day. If calculated according to Pluto, his update volume is beyond the standard.

  If the 243 earth days of Venus are used to calculate

  Ahem, let’s get down to business.

all in all.

  Under this distance condition, the image recorded by the camera is very blurry.

   It is very difficult to observe with the naked eye, let alone see its outline.

  But—here comes the point, there is one exception.

   That is the phase of planetary opposition.

  Some old color critics may read this word separately, but in fact, it refers to a special astronomical phenomenon.

  The so-called opposition of stars.

   It refers to an astronomical phenomenon that it moves roughly in a straight line with the earth and the sun during its revolution around the sun, and the earth is just between the sun and the stars.

  A star is at its brightest when it is at opposition, and this is generally the best time to observe it.

  For example, two days after readers read this chapter, that is, July 20, 2022, is the moment when Pluto will oppose the sun.

  A few days before and after the 20th, stay until the sun goes down every day.

  Pluto will rise above the eastern horizon and be visible almost all night long.

Of course.

  Here still refers to the astronomical telescope.

  Everyone knows that the orbits of planets in our system are all ellipses.

   Among them, Pluto is the outermost of the solar system, and its average revolution speed is only about 4.7 km/s.

  The earth is relatively inner, with an average revolution speed of 30 km/s.

  So almost every once in a while, Pluto will be overtaken by the earth, passively forming an opposition phenomenon.

   And it just so happens.

   September 15, 1843, was an opposition node of Pluto, and it was the brightest one in a hundred years.

   Another piece of knowledge is mentioned.

   That was before the invention of the radio telescope in 1937, the core factors that determined the observation effect were only the aperture of the telescope and the material of the lens.

   For example, Tombaugh, the discoverer of Pluto in 1930.

  The astronomical telescope he used is only 42 inches, which is 1066.8 millimeters, which is much smaller than the "Tadoro" in the open space now.

   After all, the Lowell Observatory where Tombaugh works is a private observatory after all.

  Although the founder Lowell Thiela is rich, it is still not enough compared to the Greenwich Observatory.

  The reason why Tombaugh was able to discover Pluto is largely due to good luck-Lowell's original purpose was actually to find life on Mars.

   Horizontal comparison.

   The Naga telescope used by Tombaugh in 1930 was not even ranked in the top ten in Europe in 1850.

  The actual ranking is about 13-15, which is similar to the treasure of the town hall of Muchachus Rock Observatory.

   More critically.

   Pluto is the only dwarf planet known to have an atmosphere.

  When Pluto is at its perihelion.

  The atmosphere will be in gaseous state.

   And when Pluto is at its aphelion.

  The gases in the atmosphere will condense due to the low temperature and fall like snowflakes.

  So in photos, its image feedback will be infinitely close to the concept of 'realism'.

   Therefore, under the blessing of the above reasons.

  In 1843, before and after Pluto opposition, some photos were taken, which can be called the clearest Pluto photos of this era.

   Magnify these photos with a magnifying glass, you can barely see a small bump, which is a satellite of Pluto

   Charon.

Of course.

  The reason why Xu Yun’s hands trembled was not because of the simple fact that Gauss discovered the ‘Conan Star’ satellite, but because

"Strange."

   I saw Gauss scratching his hair a little irritably, and said inexplicably:

   "The angular diameter of Conan is 0.065″-0.115″, and the oblateness is less than 1%, which means that the inclination angle of its rotation axis will be very, very large.”

"In this case, it can have a companion star, then this companion star will be tidally locked first, and secondly, its diameter can never be so small - its ratio to Conan's star is at least larger than that of the earth and the moon. .”

   "But in this way, the center of mass of Conan's star must be outside the star, so there is a problem with the deviation parameter we calculated before."

"What has actually happened."

  Gauss's brows were tightly knit together, his fingers tapped on the table regularly, his expression was dignified and puzzled.

  According to his previous calculations.

   There is a high probability that there will be satellites around Star Conan, and the number may be quite a few. After all, this is a very common thing in the universe.

   Even if it is such an unlucky person as the earth, there is a moon to accompany it.

   But the presence of a companion star is surprising

  The concept of a companion star is relatively common in stellar systems, such as binary star systems, three-star systems, etc.—the famous three-body system is a three-star system, and the prototype is Nanmen II.

  The companion star of the sun has not been discovered yet. The previous scientific speculation about the companion star of the sun is on the other side of the sun, but this guess has been denied now.

  The relatively marketable one is called the Nemesis hypothesis, also known as the dark companion star hypothesis—if you can’t remember it, you can divide it into Neme+sis, ahem.

  This hypothesis has been put forward for several years. It believes that the sun has a companion star similar to a red dwarf that exists near the Oort Nebula.

  The perihelion point is one light-year, and the aphelion point is three light-years.

  This hypothesis can explain the periodic mass extinction of the earth, but recently there is a lot of meteorite evidence that the impact of meteorites on the earth is not periodic, so the acceptance of this hypothesis is still not high.

Of course.

   Compared with stars, it is not uncommon for planets to have companion stars.

  For example, in the star system HD158259, there is a planet with five companion stars.

   But the question is where is the distance of Conan star:

   If the companion star is small, it is unlikely to be captured by a black and white camera anyway.

   Only when the volume reaches a certain scale—for example, the diameter is one-third or even one-half of the host star, it may be recorded.

  But once the companion star reaches this magnitude.

  Then the longitude of its ascending node is at least above 200, and the orbital inclination cannot be lower than 0.050.

Thus.

  A new problem arises:

  There is such a huge star, why is the value they calculated before correct?

for example.

   There is a piece of sand in front of you. It is known that a 50-jin iron ball fell from the sky.

  You determined its landing speed through deduction, and calculated the impact of sand resistance, and finally determined that the iron ball will stop at a place one meter underground.

   Then you took the shovel and dug one meter underground.

   Sure enough, you successfully found the iron ball.

  Everything seems to be fine, we can open champagne, right?

  But when you weighed it, you suddenly discovered that this iron ball is not fifty catties, but tmd is seventy catties!

   The landing speed remains the same, and the resistance of the sand remains the same.

  According to the calculation of 1/2MV, it is obviously impossible for the 70-jin iron ball and the 50-jin iron ball to stagnate in one area.

   But the actual result is over there:

   It just appeared one meter below the ground, and there was only a few millimeters of error at most.

   And unlike examples, the placement of the planets is not deceiving, it just hangs there.

  Thinking about it this way, there is only one possibility left:

   Some unknown force reduced the kinetic energy of the iron ball to the order of fifty catties after it hit the ground.

   Then Gauss thought of something again, and saw him pick up the paper and pen again, and quickly calculated on the table.

   More than ten minutes passed.

  Gauss took a deep breath, his expression thoughtful:

   "Sure enough, whether it is the Conan star itself or the influence of the companion star, there are still some problems with the orbit of Uranus."

  Think here.

  He turned his head involuntarily, looked at Xu Yun solemnly, and said:

   "Student Luo Feng, do you think there is such a possibility?"

   "It is somewhere farther away, in the depths of the starry sky as far away as possible."

   "There is also a huge, undiscovered planet that is exerting a gravitational pull on Conan and its companion star"

   Hear this statement.

  Xu Yun's pupils shrank suddenly!

   Sure enough.

   Accidents still happen.

   A few seconds passed.

  He took a deep breath and didn't answer Gauss's question.

   Instead, he took the ax out of his body, stuffed it into his mouth, and began to chew.

Um.

  Fortunately, I was resourceful, so I found a pastry shop to order an ax-shaped bread, which tasted pretty good.
